Flourish Comprehensive NOT working!!!

0

I've read great stuff about Seachem Flourish everywhere but it just won't work for my plants...i've added 1.5ml (the correct dosage for my tank) TWICE over the past week with no noticeable results :/ the leaves on most of the plants are showing an Iron deficiency i.e brown/yellow outlines here and there....i have a feeling it's my lighting that's the problem (10 watt fluorescent tube over an 18G tank)...Also, i tried to attach a picture of my plants to this thread but when i click on 'upload', an exclamation mark comes up next to the file in the attachment window - what's that all about?? i'm totally new here guys so any help would be greatly appreciated!!!

Try resizing you pics to 800 X 800 pixels and you should be able to up-load them

What type of plants are we do you have in your tank?

If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease."Not using a quarantine tank is like playing Russian roulette.

Added the stuff and waited all of one week? Uh, hate to tell you but these are plants! They do not respond to proper conditions in just a few days. If you have deficiencies, that could take new growth before seeing effects. Also, don't overdose Flourish - that stuff (any fert) can start to become toxic at higher levels; iron is very bad to overdose even just a little -at least from my reading. As for Flourish, I've had a very bad experience with that stuff with fish. So, when I had plants, I only dose the specific ferts I need at levels that are safe (I use an iron test kit to confirmed those levels for my tank) -others have no issues but I'd keep to levels the instructions call for.

Knowledge is fun(damental)

A 75 gal with eight Discus, fake plants, and a lot of wood also with sand substrate. Clean up crew is down to just two Sterba's Corys. Filters: continuous new water flow; canister w/UV, in-tank algae scrubber!! Finally, junked the nitrate removal unit from hell.

I find you have to wait two or three weeks (minimum) to really notice results. Your light levels are very low so that will slow growth results further - meaning it might be a month before you can track any changes.

@Cermet
Don't worry dude, i was extra careful about the dosage and i'm fully aware of what an overdose of Flourish does to a tank...anyway, i expected results within a week from all the reviews i read of plants doing a 180 within the said time period ^_^

Plants need 3 main things for growth: carbon, fertilizer and light. The one present in the least quantity is the limiting factor and excess amount of the other factors will not accelerate growth unless the factor present in the least quantity is grout up.
